Your file makes use of third-part addons, I cannot open it.
You shouldn't be using Lite Tween as a third part addon anymore when Construct 3 provides a standard behavior (Tween).
Are you sure you DID respect the autoplay restriction and did make sure that your player HAS to touch the screen BEFORE trying to play any sound ?
This is not a bug in Construct, it is a requisite from apple products/browsers on mobile, and something you have to strictly follow for your audio engine to initiate as intended (especially on iOS).
